Biaxial tensile geogrid

Plastic geogrid is a square or rectangular polymer mesh formed by stretching. It can be one-way stretching or two-way stretching depending on the stretching direction during its manufacture. It punches holes in an extruded polymer sheet (the raw material is mostly polypropylene or high-density polyethylene), and then performs directional stretching under heating conditions. The one-way stretched grille is only made by stretching the plate along the length direction, while the two-way stretched grille is made by continuing to stretch the one-way stretched grille in the direction perpendicular to its length.
) br/> During the manufacturing of plastic geogrids, the macromolecules of the polymer will rearrange themselves with the heating and elongation process, strengthening the bonding force between the molecular chains and achieving the goal of improving its strength. Purpose. Its elongation is only %~% of the original plate. If anti-aging materials such as carbon black are added to the geogrid, it can have better durability properties such as acid resistance, alkali resistance, corrosion resistance and aging resistance.
) br/> br/> Bidirectional geogrid
) br/> Bidirectional geogrid is made of polymer
through extrusion, plate forming and punching process and then longitudinally , formed by horizontal stretching. The material has great tensile strength both longitudinally and transversely. This structure can also provide an ideal interlocking system for more effective force bearing and diffusion in the soil, and is suitable for large-area permanent bearings.
